crypto.tpliot.decrypt
---------------------

You can use this test case to decrypt the communication between TP-Link smart
devices and Kasa home application.


**Usage details:**

.. code-block:: console

   ef> run crypto.tpliot.decrypt -h

Examples
^^^^^^^^

The input data ``-d`` would be a HEX string from the captured communication.

.. code-block:: text

   ef> run crypto.tpliot.decrypt -d 00000066[...]ae9ee39ee3

   [...]
   [*]Decrypted Data :{"context":{"source":"46a4d58b-6279-432c-ae23-e115c2db8354"},"system":{"set_relay_state":{"state":0}}}
   [+] Test crypto.tpliot.decrypt passed


.. note::

   The HEX input should be without the ``0x`` prefix.
